Dual-lens diagnostic. Every operator decision viewed simultaneously through the Investment-side ROI lens and the LOT-side foregone-earning lens. Closes the gap where operators frame spending as expense without recognizing the foregone-earning consequence. Open item: whether this stands as its own IP entry or lives implicit inside the full Lost Opportunity Tax primary entry once that gap closes.

Explanation

Most operators run every spending decision through a single lens: what does this cost, and what return does it generate. That’s the Investment-side ROI lens, and it’s necessary but incomplete. This dual-lens diagnostic insists on a second, simultaneous view — what is being foregone by not making this investment, which is the [Lost Opportunity Tax] side of the same decision.

The gap this closes is subtle but consequential. An operator who only asks “what does this cost me” will systematically underinvest, because that framing treats every dollar spent as pure expense with no visible counterfactual. Asking the second question — what am I foregoing by not spending this — surfaces the cost of inaction alongside the cost of action, which is the only way to actually compare the two honestly rather than defaulting to the option that looks cheaper on paper today.
